1930. N, RASSIER AUTOMATIC DOOR KEEPER Filed Oct. 28, 1929 2 sheets-sheet 2 Il l' O/ Inventor f/J'w/r Attorney Patented Oct. 28, 1930 UNITED STATES The present invention relates to an auto' Another very important object of the in" l vention resides in th-e provision of a structure of this nature which is automatic in its operation. i

A still further very importantv object of the invention resides in theV provision of a structure of thisY nature which is simple in its individual parts, inexpensive to manufacture, strong and durable, thoroughly eli-` Vcient and reliable 1n use and operation, and

otherwise well adapted to the purpose for which it is. designed.

With the above and numerous other objects in view as will appear as the description proceeds, the invention resides in certain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawing: Figure lis a fragmentary side elevation of a doorway such as is used on a freight car showing my improved structure, Figure 2 is a sectional view taken vertically and substantially on the line 2 2- of Figure l,

Figure 8 is ahorizontal section taken substantially on theline 3 3 of Figure l, and Figure 4 is a fragmentary detail side view showing the rail on the inner side .of the door. Y i

Referring to the drawing in detail it will be seen that on the side edges ofthe door. Way there are mounted channel irons 5 at.- tached tothe side wall 6. Doors 7 are hung to slide in the usual well known manner. Rails 8 are horizontally disposed transversely across the inner faces of the doors 7.

On the outer edges of the doors are angle irons 9 vertically disposed'. Brackets l0 mounted on the side wall 6 one adjacent each channel iron 7 and keepers K are rockably NORBERT nAssIER, or ansnnngnimtnsobra;
